If a calculator shows 8E9, what would it be in standard notation?

If a calculator displays 8E9, it represents the number 8 multiplied by 10 raised to the power of 9. This means you move the decimal point in 8 nine places to the right. So, in standard notation, 8E9 equals 8,000,000,000. That's eight billion—definitely a big number! Understanding scientific notation like this is super useful in fields like science and engineering, where we often deal with very large or very small numbers. It simplifies writing and calculations, making it easier to communicate those hefty numbers more clearly. Just remember, the "E" stands for exponent, and it’s like shorthand for the "times ten to the power of" concept!
